Low-noise environmentally-friendly pneumatic chain saw

Abstract

The invention provides a low-noise environmentally-friendly pneumatic chain saw. The low-noise environmentally-friendly pneumatic chain saw comprises a saw blade, a housing, an air-water linkage waterbreak protector arranged at the outer part of a machine body, and a water outlet in the air-water linkage water break protector, wherein a disc base is arranged on an outlet of an exhaust pipe of a pneumatic motor; a sound guide pipe is arranged on the disc base; a main sound channel which communicates with the outlet of the exhaust pipe of the pneumatic motor is arranged in the sound guide pipe;a sound return sleeve pipe of which the front end is closed is arranged at the outer part of the sound guide pipe in a sleeving manner; the tail end of the sound return sleeve pipe is fixed to the disc base; a secondary sound return sleeve pipe of which the front end is open is arranged at the outer part of the sound return sleeve pipe in a sleeving manner; the tail end of the secondary sound return sleeve pipe is fixed to the disc base; a spraying pipe is arranged on one side of the saw blade; a spraying head is arranged at the front end of the spraying pipe and right faces the saw blade; the other end of the spraying pipe is fixedly connected with a water inlet rubber pipe; and the water inlet rubber pipe is connected with the water outlet of the air-water linkage water break protector.According to the low-noise environmentally-friendly pneumatic chain saw, dust can be effectively removed, possible high temperature and spark phenomena can be eliminated, and safety production is guaranteed; and the structure is compact, the number of technological equipment is simplified, universality is good, a cooling emulsion is replaced, and the low-noise environmentally-friendly pneumatic chain saw is more environmentally-friendly.

Description

technical field [0001] The invention relates to a pneumatic tool, in particular to a low-noise and environment-friendly pneumatic chain saw. Background technique [0002] Powered by compressed air, the pneumatic saw blade is mainly used for cutting or cracking wood, non-metallic pipes, coal, concrete, masonry and other materials, and is also suitable for cutting operations on soft rock and walls. During the working process of the existing pneumatic saw blades, the air pump produces strong noise and dust. Most of the methods to eliminate noise are to open an exhaust hole on the motor casing and add an exhaust hood to exhaust the air, so that the noise can be released quickly, but After testing, the noise of the exhaust hole during operation reaches 80-90 decibels, which is harmful to the body. The dust aroused by the exhaust port can easily block the exhaust hood. In addition, although the coolant system in the middle of the chain plate directly flushes the saw blade to play...

Problems solved by technology

During the working process of the existing pneumatic saw blades, the air pump produces strong noise and dust. Most of the methods to eliminate noise are to open an exhaust hole on the motor casing and add an exhaust hood to exhaust the air, so that the noise can be released quickly, but After testing, the noise of the exhaust hole during operation reaches 80-90 decibels, which is harmful to the body. The dust aroused by the exhaust port is easy to block the exhaust hood.

In addition, although the coolant system in the middle of the chain plate directly flushes the saw blade to play a cooling role and has a local dust reduction function, it is only for the cutting part of the saw blade and cannot affect the dust and fine particles aroused around the saw blade. Most of them are artificially spraying a large area in the working corner, but water resources are wasted, the work is not synchronized, the effect of dust suppression is limited, and sparks cannot be effectively eliminated, which brings certain risks to safe production
